FDomain operations on Channels.

Variants

CreateChannel

Create a new channel in this FDomain and return both its ends.

Fields

handles: [NewHandleId; 2]

responder: ChannelCreateChannelResponder

ReadChannel

Read a message from a channel. This method will fail if the channel is currently being read using the streaming read functions.

Note that this method is not like zx_channel_read in that it will not return SHOULD_WAIT but will instead delay returning until there is data to return.

Fields

handle: HandleId

responder: ChannelReadChannelResponder

WriteChannel

Write to a channel. Handles are always consumed.

Fields

handle: HandleId

data: Vec<u8>

handles: Handles

responder: ChannelWriteChannelResponder

ReadChannelStreamingStart

Starts reading from the given channel. Data is returned via the ChannelStreamingData event. That event will occur repeatedly until ReadChannelStreamingStop is called for the same handle or the event indicates the handle is closed.

Fields

handle: HandleId

responder: ChannelReadChannelStreamingStartResponder

ReadChannelStreamingStop

Stop asynchronous reading from the given channel.

Fields

handle: HandleId

responder: ChannelReadChannelStreamingStopResponder

#[non_exhaustive]

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: ChannelControlHandle

method_type: MethodType
